bigoc - first, you are correct, the stressor has nothing to do w/meds but you mentioned it your initial post and I was pointing out that stressor has no bearing on how bad your PTSD is, now. Whether you take meds should not have any bearing on your PTSD rating. They do usually state whether or not the claimant takes them, in the C&P report, and to me that could count against a claimant, as most claimants do better on meds, which could but shouldn't lower the rating.
About the 100%, I have no problem w/a claimant working, and, in fact, suggest that they work as long as possible. I do object to someone rated TDIU or 100%, for PTSD, working. Many come here wanting to work after receiving a 100% award. They don't seem to realize that they are getting paid because they can't work and if they can they should give back the money.(jmo) I worked as a fulltime career level firefighter/EMT and feel the reason I was so good at my job was my military training and what I eventually came to know as PTSD.
Good luck!
